Well, I see Mikewalsh has beaten me to it by publishing an OpenOffice portable. There may be occasions when you'd prefer an SFS and the attached pet can be used with any OpenOffice version 4 (maybe others): OpenOffice offers a main download, but also other versions including older, language specific and IIRC 32-bit.
Having menus to OpenOffice's component applications --such as writer, spreadsheet and presentations-- means you can open those directly. But perhaps more important, you can set those components as the defaults and associate them with file-types so that the appropriate application will open by clicking a datafile of its associated file-type.
To use the pet you first have to download a 'deb' from https://www.openoffice.org/download/index.html after also selecting your preferred version. I recommend that after making the selection that you Right-Click the box named "Download Full Installation" and select Copy Link. Open Menu>Internet>Uget and allow that to do your download. The tar.gz to be downloaded is 159 Mb and Uget will re-continue interrupted downloads.
Once you obtain the tar.gz, use UExtract or pExtract to extract it. File-browse into the extracted folder within which you'll find a folder named DEBS.
Leave the window to it open. Right-click an empty space somewhere else, from the pop-up Menu select New>Directory and give it an appropriate name. As the above graphic shows I chose OpenOffice64. Left-Click that folder to open it. Now copy all the debs from the other Window into that folder. A quick way is Right-Click an empty space, then press Ctrl-a. Everything will be highlighted/selected. Left-PRESS, hold, then drag any file from there into the other folder and select Copy. All will be copied. As you don't want the folder named 'desktop-integration', Right-Click it and select Delete from the pop-up Menu.
Now download, then SFS-Load PaDS, https://www.forum.puppylinux.com/viewto ... 6355#p6355. Then Right-Click the folder you created now holding the debs. PaDS will unpack them and create an SFS in /root. A Window of /root will open when PaDS finishes.
Move the SFS out of /root before loading/testing. If you SFS-Load it from /root, when you unload it will be deleted.
Then, having downloaded the OpenOffice-menus.pet, install it. You may have to 'Fix-Menus' for the OpenOffice applications to appear on your Menu.
The pet places a 'Quick-Launcher' of applications on the Taskbar. If you don't want that, file-browse into /root/Startup and delete the script named OOQuick.
